3‐Methoxymorphinan ( 1 ) was converted to the corresponding N ‐chloro derivative 2 by treatment with aqueous sodium hypochlorite. Upon exposure to methanolic silver nitrate, 2 was rearranged to the carbinolamine ether 3 . In addition, considerable amounts of the dechlorinated morphinan 1 were formed. The structure of 3 was secured by spectral analysis and its degradation to the hexahydroindoline derivative 4 . The observed skeletal rearrangement of 2 which requires the migration of an alkyl group is discussed in terms of a nitrenium ion.
